_calculateOpenAngle()

TESTABLE_INLINE_STATIC uint16_t _calculateOpenAngle	(	FuelSchedule &	schedule,
		uint16_t	pwDegrees,
		uint16_t	injAngle
	)

Compute the injector open angle for an injection channel.

Parameters

pwDegrees	How many crank degrees the calculated PW will take at the current speed
tdcOffset	The number of crank degrees until cylinder is at TDC (at rest)
injAngle	The requested injection angle

Returns

uint16_t
